Laser Micromachining
As the electronics industry advances, laser micromachining as a versatile process requires more precise optical systems and sophisticated hybrid control systems of hardware and software in recent years. We have accumulated our own optical design and precision system control technology over an extended period of time through the development of PCB lithography systems. Today, we are striving to lead the market with differentiated laser processing solutions by expanding our accumulated core technologies into the field of laser micromachining.

Our dedicated optical design team develops optical systems that enable more differentiated performance in laser micromachining through collaboration with process engineers with extensive practical experience and in-depth theoretical knowledge in laser applications.
Laser-Lift Off equipment for Flexible OLED is one of our representative laser application equipment. The line beam optical system used in this equipment must be coupled with a number of high-power ultraviolet lasers, so its high thermal stability and durability are absolutely required. In order to develop such an optical system, high technical know-how is necessary in all stages from optical design to manufacturing, so only a few overseas optical companies were able to meet the needs of customers in the meantime. We are is the only company in Korea that has succeeded in developing a line beam optical system with its own technology and is being evaluated for its high quality in the mass production line of customers. -
As the form factor of digital devices changes, laser micromachining of display materials simultaneously demands a high precision and high speed processing, which was not previously possible. To meet this demand, we are focusing on developing precision system control technology along with optical systems specialized for ultrafast pulse lasers. In particular, Our system control technology is optimized for high-speed, high-precision machining based on a hybrid of hardware and software.Today, Philoptics' laser micromachining technology, which combines each of our core technologies of optical and control system so as to show differentiated performance, is significantly contributing to leading the market for the customers.
3D Inspection Technology
Philoptics' optical non-contact 3D inspection technology satisfies the high-precision inspection of the the sub-micron required from various high-tech industries of the semiconductor, display, and rechargeable battery sectors.
In our 3D inspection technology, the phase map of the object's surface is extracted through high-speed algorithm on image information acquired by projecting a specific light pattern on the object. The 3D surface information formed in this way is determined whether it is defective or not based on the criteria set by the user.
- Light pattern projection
- Image acquisition
- Phase map generation
- 3D model creation
- Defect detection
Although working in a intuitive way, the technology can provide a solution for simultaneously performing large-area and high-precision inspections due to our unique optical system structure and detection algorithm.

Conventional laser-interference based 3D inspection technology provides high precision at the level of tens to several nm. But, it requires a long inspection time even for a small area of interest so it can be applied only to sampling and limited spot inspection. In addition, stereo vision based 3D inspection technology enables large-area & high-speed inspection, but is not working for high precision.
Our technology can be applied not only for R&D purposes but also for mass production purposes, as it enables high-speed and large-area inspection while providing a level of inspection precision equivalent to that of interference method technology. Our 3D inspection technology has the following key advantages: -
Detection of defects at the size of sub-micron to several nm
Inspection of a large area with extended FOV
Inspection of reflective and non-reflective surface
Reduced inspection time through a high-speed calculation algorithm
Free from environmental circumstances such as vibration and noise
